The Roman Agora. Hadrian's Library, Athens. Greece.

Adjacent to the Ancient Agora is the site of the Roman Agora. While it may all seem like one site, these buildings were constructed later, and construction eventually moved on to the site of the Ancient Agora. One of the easily recognizable sites here is the Tower of the Winds.

On the edge of the Roman Agora is the ancient Hadrian's Library, founded by Emperor Hadrian in AD 132. Even later, during Byzantine times, three churches were built near the site of the library.

You can see one wall of Hadrian's Library and ruins of the Roman Agora from the street, but if you want to explore further, you can buy a ticket and walk through the ruins.
